Hello,
I am trying to make the transition from Windows to Zorin and am having an issue regarding my touch screen monitor:
My primary monitor is a Dell U2212HM (No touch screen)
My secondary monitor is a HP L6015tm (It is touch screen)
When I attempt to use the touch screen on the HP it thinks I am touching the Dell
On windows I am able to configure which monitor is touch screen in the "Tablet PC Settings" is there an equivalent for this in Zorin?
I think there isn't such function in gnome yet only in kde.
You could switch to Xorg if you are using Wayland (logout and at login click on your username then a cog wheal appears at the bottom right corner, there select "Zorin Desktop on Xorg".
Then you can follow this site to find out the id of the touchscreen and the monitor names and assign it.
I'm not sure if the script will work which is shown there because I found no date and haven't tested it. But you could try the first steps without the script.
In Wayland it seems to be even more complicated. Here is another guide which shows it for Xorg. You don't need to disable Wayland completely as shown in step 1. Just switch to Xorg at loginscreen.
Don't follow the steps for Wayland there which installs sway.
For Wayland I found this thread but it is not very clear what to do:
In archwiki is said that there is no way to achieve this in Wayland except with Sway.
How do I know what I am using now? I am completely new to linux and am petrified of anything in terminal since I have no idea what im doing.
I would enter in terminal
xinput list
and make a screenshot of the output,
one time connected with your touchscreen monitor and one time disconnected (unplug it or turn it off). Then you can compare the outputs and look what is the device that has changed. It is probably a "pointer" not a "keyboard" in the list. Then note the id.
Then connect the monitors and enter
xrandr
which will show you the names of the names of the connected monitors.
If you have problems to distinguish which one is the touchscreen and which one the other (if they have the same resolution), it may help to change the resolution of one of them for this test or look if one uses HDMI and one DP.
After that use this command to assign the id of the input device (e.g. id=5) to the monitor (e.g. DP-1)
xinput map-to-output 5 DP-1
If you like you can post the two screenshots of "xinput list" here.
You don't need to be afraid of using those commands. If you made something wrong just reboot then the setting is reset.
This is my input list with it attached:
And this is without:
It looks like the touch screen is id 9
I looking at the connected monitors I found that DP-1 is the Dell and DP-2 is the HP
So at this point I would need to type "xinput map-to-output 9 DP-2"? Does that sound correct?
Also if my setup changes in the future how to I un-map it?
Yes, I would try it with this command. That looks good to me.
I'm not sure if the ids are always the same after a reboot. At the moment after each reboot you would need to enter this command again because the settings are reset. If I were you I would run the 'xinput list' and 'xrandr' command after the next reboots to see if the name/id for the monitor stays the same.
If yes, you could add the command to autostart programs (create a new entry there, name it as you want and enter the command from above). If it doesn't work try it with a time delay, e.g. 4 seconds
"sh -c 'sleep 4 %% xinput map-to-output 9 DP-2'"
If that doesn't work either, we'll try a script.
For future changes you would have to remove the command from autostart, then after a reboot the settings for the touchpad monitor will be reset.
It worked! I restarted to see if my inputs and outputs changed and they did not so I put the command in autostart without the sleep and it works like that.
Thanks!
